Wedding cake auto HELP

Yes, unfortunately this looks alot like leaf septoria disease. Read the article from breadboardjohnson below. Good luck

Ahh no, that looks absolutely terrible. Dont panic and dont do anything rash, make sure your next move is calculated because if you do something wrong those plants will be more gone than they already are. I know everyones first assumption is nutrients but I found this info on a disease: https://www.grasscity.com/blog/post/yellow-leaf-spot-and-marijuana-plants

I agree with Sirsmoke :) Defo looks like a phos overdose which if not flushed will probably affect your yield though best of luck and flush her for a few days like Sir said and see how you go :)

This looks like a lockout to much PK blocks cal Or you got a wrong pH. Just give pH balanced water for the next 2-3 times and look how she responds.
